Herein, we demonstrate a successful preparation method of ionic liquid functionalized POSS hybrids by quaternization of imidazole salt with Octa-(ɤ-chloropropyl) POSS. A novel photofunctional hybrid soft material POSS- min-[Eu(tta)₄] (tta:2-thenoyltrifluoroacetone) was reported via an ion-exchange reaction between imidazolium-based POSS(POSS-min-Cl) and lanthanide complex [Eu(tta)₄]^-. The obtained hybrids were extensively characterized by FT-IR, ¹HNMR, ¹³CNMR, UV–Vis, PL and TGA in detail. What's more, POSS-min-[Eu(tta)₄] displays higher fluorescence intensity, longer lifetime and higher thermostability than corresponding pure complex. More significantly, POSS-min-[Eu(tta)₄] exhibits the improvement of photo physical properties (ƞ = 53.73 %) and is selected as the representative sample to examine the potential fluorescence sensing of metal cations. The hybrid POSS-min-[Eu(tta)₄] has selective fluorescent quenching effect for different metal ions, especially for Cu²⁺. These results provide meaningful data for the multi-component assembly and responsive luminescent of photo functional hybrids based on modified ionic liquid and lanthanide, which can be expected to have potential application in organic light-emitting devices(OLED) or sensor.

在本文中，我们证明了通过咪唑盐与Octa-（ɤ-氯丙基）POSS季铵化成功制备离子液体功能化POSS杂化物的方法。通过基于咪唑鎓的POSS（POSS-min-Cl）与镧系元素络合物[Eu（的复合物）的离子交换反应，报道了一种新型的光功能杂化软材料POSS- min- [Eu（tta）₄ ]（tta：2-thenoyltrifluoroacetone） tta）₄ ] ^-。获得的杂种通过FT-IR，¹ HNMR，¹³ CNMR，UV-Vis，PL和TGA进行了广泛的表征。而且，与相应的纯配合物相比，POSS-min- [Eu（tta）₄ ]显示出更高的荧光强度，更长的寿命和更高的热稳定性。更重要的是，POSS-min- [Eu（tta）_图4 ]显示出光物​​理性质的改善（ƞ＝ 53.73％），并且被选为代表性样品以检查金属阳离子的潜在荧光感测。POSS-min- [Eu（tta）₄ ]杂合物对不同的金属离子，特别是Cu ²⁺具有选择性的荧光猝灭作用。这些结果为基于改性的离子液体和镧系元素的光功能杂化体的多组分组装和响应发光提供了有意义的数据，有望在有机发光器件（OLED）或传感器中具有潜在的应用。
